[PATCH] swsusp: use bytes as image size units

2006-02-01T16:53:12+00:00

Make swsusp use bytes as the image size units, which is needed for future
compatibility.

[PATCH] swsusp: make image size limit tunable

2006-01-06T16:33:42+00:00

Make the suspend image size limit tunable via /sys/power/image_size.

It is necessary for systems on which there is a limited amount of swap
available for suspend.  It can also be useful for optimizing performance of
swsusp on systems with 1 GB of RAM or more.

[PATCH] swsusp: improve freeing of memory

2006-01-06T16:33:40+00:00

This patch makes swsusp free only as much memory as needed to complete the
suspend and not as much as possible.   In the most of cases this should speed
up the suspend and make the system much more responsive after resume,
especially if a GUI (eg.  X Windows) is used.

If needed, the old behavior (ie to free as much memory as possible during
suspend) can be restored by unsetting FAST_FREE in power.h

[PATCH] swsusp: introduce the swap map structure

2006-01-06T16:33:40+00:00

This patch introduces the swap map structure that can be used by swsusp for
keeping tracks of data pages written to the swap.   The structure itself is
described in a comment within the patch.

The overall idea is to reduce the amount of metadata written to the swap and
to write and read the image pages sequentially, in a file-alike way.  This
makes the swap-handling part of swsusp fairly independent of its
snapshot-handling part and will hopefully allow us to completely separate
these two parts in the future.

This patch is needed to remove the suspend image size limit imposed by the
limited size of the swsusp_info structure, which is essential for x86-64
systems with more than 512 MB of RAM.

[PATCH] swsusp: resume_store() retval fix

2006-01-06T16:33:21+00:00

- This function returns -EINVAL all the time.  Fix.

- Decruftify it a bit too.

- Writing to it doesn't seem to do what it's suppoed to do.

[PATCH] swsusp: two simplifications

2005-10-31T01:37:15+00:00

The following patch simplifies the progress meter in disk.c:free_some_memory()
and makes disk.c:pm_suspend_disk() call device_resume() explicitly in the
suspend path.

[PATCH] swsusp: rework memory freeing on resume

2005-10-31T01:37:14+00:00

The following patch makes swsusp use the PG_nosave and PG_nosave_free flags to
mark pages that should be freed in case of an error during resume.

This allows us to simplify the code and to use swsusp_free() in all of the
swsusp's resume error paths, which makes them actually work.
